"At 17, I wanted to die so badly, it was the only way I could decide what I wanted to do with my life."
"Why? That's how you lost the desire to live?"
"It's the only way I don't have to worry about not living a certain way anymore."

Yi-Kuang Wu never expected to live past the age of seventeen, nor did she expect to become a teacher, nor did she anticipate that thirty-eight minutes after the school bell rang, one of her students would leap from the roof.

When she rushed to the scene, the girl's body was no longer there, but the crowd of parents, a large bloodstain on the ground, and the ambulance siren in the distance, let Wu Yiguang believe that an invisible and severe judgment on her has already begun.

The death of the young girl puts the 100-year-old gifted girls' school in a state of anxiety.

Teachers and students desperately need an answer, either to allay their fears, to deal with the media, or to reassure themselves with a clear delineation of power and responsibility - I had nothing to do with her death.

As a classroom teacher, Yi-Kuang Wu tries to clarify the reasons for the young girl's death, to find an answer for people and for herself.
